For p=0.1, the activity coefficient (gamma) of M2+ is 0.45 while gamma of X- is 0.80. Calculate how many milligrams of MX2 dissolve in 478 mL of solution whose p=0.1. The molar mass of MX2 is 183 g/mol and its Ksp is 3.2 x 10-8. You can assume that ionic strength is caused by the presence of inert ions.
